CONSTRUCTION TIE.

Original m. 1,472,194,

To all whom it may concern: I

Be it known that we, CHARLES P; Sonar.- nm and ROBERT M. BROWN, citizens of the United States, both residin at Chicago, in 6 the county of Cook and te of Illinois,

have invented certain new and .useful Improvements in Construction Ties; and we do'hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same. J r

This invention relates to building structures, and particularly structurw of concrete or the like havin an outside veneer of brick, tile, cut stone other suitable building blocks.

One of the principal obj ects of the invenfor binding structural elements toa. surface of concrete or the like. Other objects are to tie a veneering of brick or" the like to a main building wall,

ceiling or floor of concrete or the like, in a strong, simple and eflicient manner; to facilitate erection of structures of the character mentioned; to improve the'means of attachment; to avoid the necessity of using special forms of tile, bricks or other building blocks, and otherwise to simplify and improve the building operations of buildin structures. he invention consists in the combination of elements and details of construction hereinafter more fully described, illustrated in the accompanying drawings, and defined in the appended claims.

In the drawings, in which is illustrated an improved embodiment of the invention- Figurel is a fragmentary elevation of a wall of concrete or the like, after the form has been removed, a portion of an outer covering of veneer wall being shown partway completed, and adapted to be attached thereto in accordance with the principles of this invention.

whole the main portion of a building wall,

and 2' represents columns or other massive and strong elements of the wall. These columns areintended to be made of concrete or A facing or veneer layer of brick, tile, or the like is illustrated at 3. This facing layer must be anchored to the main wall structure, as it is relatively thin, being constructed as in the example shown by a single tier of blocks.

In order to tie the veneeror facing wall to the main wall structure, means about to be described are provided. Molded perpendicularly in the concrete columns or other elements 2 are vertical grooves 4, which are dove-tailed in cross section or otherwise formed wider at their bottoms than at the exterior openings thereof. These grooves, sometimes known as undercuts, arehere designated dove-tailed grooves, and may be of any desired form, so long as their bottoms are wider than the entrances thereto. In order to strengthen these grooves, besides forming them, they are lined with dovetailed channel members of metal, as indicated at 5. The said members 5 are intended to be molded in the concrete with their flanges 6 embedded flush with the surface of the elements 2. "The said dovetailed grooves thus formed, extend continuously throughout-the extent intended to be concealed by the veneer or facing wall. As the facing wall 21 rises, it will be anchored to the elements-2 by key strips 7. Saidkey strips are preferably made of flat metal, each having one end provided with a dovetailed tongue adapted to approximately fill the groove in the channel 5 when the said key strip 7 is disposedwith its plane surface intersecting the axis of the groove. 95 In the form, shown, the key strips 7 are provided with shoulders at 9, which engage the surfaces of the .flush flanges 6 of the channel members. It is, apparent that these key members 7 may be the grooves, that they may be inserted edgewise in the groove and turned to a horizontal position, in which position they cannot be. ulled out of the grooves. The ends of the my strips 7 opposite the tongues 8 are in- 105 tended to overlie the course of bricks or other building blocks 3, and to be placed thereon. The saidke strips may be made of any length desire in conformity with the thickness of the veneer wall and its 110 adjusted freely in since the key strips 7 imbedded in proximity to the main elements of the walls 1 and 2. Adjacent the outer ends of each key strip 7 is provided a loop 10 which may be formed in anymanner thereon, but which is preferably-struck u from the metal of the key strips 7, as il ustrated at Figure 3 of the drawings. This loop 10 is, of course, made in the usual, manner by slitti g the strip 7 a length equal to the width esired for the loop and pressing the portion between the strips out of the plane of the strip. The longitudinal strips 11 are extended between key strips 7 resting upon the same course of building blocks. Each section is referably a little longer than the distance etween centers of two adjacent key strips 7. The ends of adjacent tie stri s 11 are inserted throu h the loop 10 0 the key strip, so that t e ends overlap within said oop. Thus the tie stri 11 extend lon tudinally of a course 0 bricks or the li e to aid in tying the bricks longitudinally, and are themselves spaced from and tied to the main elements or columns 2 by means of the key strips 7. The tie strips 11 and the key strips 7 bein made as shown, of flat, relatively thin, a though tough and strong metal, do not lie fiat upon a course of bricks, and may be a layer of cement or mortar between, upon which they rest and the courses imposed above.

It will be understood that the illustrations are somewhat dia ammatic, and simply for the purpose of 0 early illustratin the invention. Such a number of key strips 7 will be used as will firmly anchor the faclng wall to the main structure. The key strips and tie strips may be inserted at any suitable distance apart as may be found necessary. As has been before ointed out, they may be anchored to the uilding at any point, are free to" be moved along the grooves and channels 4. and 5. No special'form of building block is required in order to anchor the keys, the ordinary rectangular' brick being 7 referabl adapted to be secured in accor ance wit this improvement.

We are aware that made, and numerous varied throughout a many changes may be details of construction wide range without departing from the rinciples of this invention, and we, there ore, do not purpose limiting the patent granted thereon otherwise than as necessitated b the prior art.
